Cree's (CREE-13.8%) Q2 earnings miss bodes poorly for the LED sector. Also down are LED equipment makers Aixtron (AIXG-3.8%), Veeco Instruments (VECO-6.2%), and Nanometrics (NANO-1.8%), as well as LED materials supplier Rubicon (RBCN-5.7%). Cree attributed its results to component over supply in Asia.
